What
Water Lettuce (Pistia stratiotes)Observer
alexahowanskyDescription
4 or 5 larger plants with a few smaller ones sprouting from them. Probable aquarium dump--people have been caught releasing aquarium contents here in the past, and water lettuce is known to be sold at aquarium/water gardening stores nearby. It is also a Tier 1 species in our region, so theoretically it shouldn't have come from another water body. All visible plants were within reach either by hand or by stick and were removed. Capital Region PRISM plans to get a boat out there and search for any more.

intrinsicallyknottedDescription
Only one white blob at the tip of this hemlock branch. I can’t get close enough to tell, but it might be foamy rather than wooly. May be a spittlebug rather than hemlock wooly adelgid, but I’m not sure.
